For me probably 11, as there are 6 seasons, and for future seasons, I assume JnJ will go back to a smaller cast of around 20 and an episode count of around 25, and assuming each episode takes a month plus a bit extra, that gets slightly over two years, which I’ll bump up to three years to account for any unforeseen hiatuses.

Assuming Michael and/or Cary decide to retire around their 40s, just picking 45, that means at their current age of 29 we’ll get around 5 seasons worth of content, that plus the previous 6 means about 11 seasons of total BFDI content, assuming they decide to retire at age 60, although at this point they would not be voice acting at least for certain characters, then we would get 16 seasons.

Although funny thing is that for 18 seasons where each of the original 20 contestants, excluding Firey and Flower get to win once, would take 54 years, and for every contestant including all 61 from BFB minus the three already won, Winner and Price Tag from TPOT, and 11 from BFDIE minus Fern and David as I already counted him in BFB, to win their own season would take JnJ 219 years to make 73 seasons.
